and if i use single sim..it works
device id null

Hi there, You are not alone
I am also Redmi 2 (both 1gb and 2gb ram variant) user. I was using MIUI Kitkat, then switched to Lollipop using fastboot. Later I also used CM14 (Lineage OS - N). Few hours Iater after using it I felt buggy so finally I came back to MIUI 8 (Kitkat).
I also got Baseband unknown error, I will explain how it came and what to do next..
I basically have two Jio sims. so what I did what tried using the mobile (Redmi 2 1GB) with two JIO sims at the same time, I finished the DATA from sim 1 so I tried to swap Mobile DATA from sim 1 to sim 2. And that's it.!!
My Baseband became "UNKNOWN" and phone started to reboot.
How did I fixed this ? :
First of all, I have MIUI Lollipop (LP) Fastboot (FB) Rom as well as MIUI Kitkat (KK) Fastboot Rom (MIUI versions doesn't matter).
Next what I did was, Remove the SIM cards and Memory Card from my phone and Flashed the MIUI LP FB Rom. After successfully getting into MIUI welcome screen, I turned off the phone and again fastbooted it and flashed the MIUI KK rom. Now I dont get Unknown Baseband Error, If suppose you are a Jio user.! For your kind information use the JIO sim only on Sim 1 slot and also do not use two JIO sims like me. Redmi OS hasn't got developed much to switch sims with 4G higher band LTE simultaneously . If you need you can exchange the JIO sims manually by removing the previous sim from Slot 1.
NOTE : I have flashed with "FLASH ALL" option in MiFLash software.
Good luck, I hope my essay like reply will help you.!

Kindly try and tell me, If still the problem persists then I'll give another advanced brief solution.
Cause it needs your mobile to be rooted and also needs PC + few softwares to restore your IMEI (Bandbase) :good:
Hello Friends , I have OnePlus 2 ( oxygen OS 3.6.1) with JIO on my 1st sim slot . Many times the VOLTE icons disappears from the status bar although the signal is full on the sim and the data is working .After VOLTE icons disappears I cant make any call from the sim and I dont have any other choice than disabling the sim card and re enabling it to bring the VOLTE back which is quite frustrating . Any help on this ?
Try resetting the network settings within your sim card menu. Revert if issue persists.
Hey I already tried network resetting but nothing works
perhaps reflashing the modem firmware file of 3.6.0 or 3.6.1 will solve your issue. Link is in the lineage OS 15 thread. Search for the keywords you'll get it. If you don't I'll link.
Hey send link didn't find it plz

I am also facing this issue recently.
I Tried reflashing the OS to 3.6.0 and 3.5.6 but same issue still persists. I cleaned Data and cache too.
(Jio VOLTE is now only working in SIM1 slot. Previously it used to work in SIM2 slot too. Even after flashing to older OS, facing same issue)
No success yet.

Hey guys,
Recently I flashed nitrogen is roms by soleintic,the ROM was working flawlessly without any issues...Today I went to service centre to get my device's speaker changed.After getting my device back volte was not working while previously it was working,So I thought changing swapping the sim slots would do the work I did the same and volte was working then but my data was not getting connected it was showing some random error in ipv6 and ipv4,then I again switched the sim slots and in slot 2 the data was working but volte was not working so I thought reflashing the ROM would fix the error.I reflashed the ROM again but the error was still there...So I decided to switch ROM..so I flashed PE ROM 5 mins ago but it's showing the same error pls help me I can't understand the real problem.

In short...Volte is working in slot 1 where as data is not working in it where as data is working in slot 2 but volte is not working there....The exact thing on phone info is
Ipv4:fail(2)
Ipv6:fail(2)
HTTP client test:Failed(IoException)
Flash miui rom and then flash any custom rom. I'm not sure where it'll fix the problem but chances are high
I just upgrade my Nokia 6(TA-1000) to official Android 8.0.0 (Oreo).
Then my Cellular network won't work anymore.
I live in Hong Kong, using sim card service "CMHK".
I think it is LTE/WCDMA mode.
Tried "*#*#4636#*#*" and changing the settings.
But the connection always shown IPv4: Failed(2)
The phone notification show it is connected and running 3G network.
But the upload/download speed is always 0KB/s.
Reset to factory setting already.
Before upgrade Android everything work fine.
Anyone have the same problems?
Now, what can i do....?
It seems I can't even downgrade my Android.
Only, have to wait for next update and hope it will fixed?
I think i am screwed.

No, there is a lot difference between system reset(soft reset) and recovery reset (hard reset)
Try it, may be it solve your problem

Have you tried other SIM cards, whether you work in your cell phone! Tried to register your network operator service in the settings! Set preferred network ~

I use official update.
All firmware should be correct?
BTW, I get a new sim card from ISP but cellular network still not working.
Also, tried both sim card slot 1 and slot 2 nothing work.
May be new system not compatible with my SIM card service only which is "CMHK" aka "中國移動香港".
Hope next update will fix that...

NOKIA 6
hi,
i updated my nokia 6 TA-1000 to oreo update.
i faced many issues like lte not working.
in battery saver mode launcher is stopping suddenly.
it is not detecting the sim correctly.
i didnt get network signals correctly.
Then i tried to hard reset my mobile ,after complete reset and after rebooting it stopped at language selection,i clicked lets go many times but it is not working .it got stucked there.
is there anyway to get rid of it.i asked for nokia chat support but they are asking me to take mobile to nearest service center.
if there is any solution please guide me with it .thank you in advance.
I just turn off the cellular network yesterday.
After I wake up from bed, my phone Google service can not connect from wifi(can't use email, Google store).
BUT! After reinsert my sim card and turn back on cellular network, everything working now.
Both 4G cellular and Google service all good.
May be some part of the network is cached.
So, if you encounter this problem just turn off cellular network and wait.

It seems that, the old slot 1 cached your sim card.
So, you change to slot 2 work, but you can't use SD card.
And I found that if you wait a long time the cache will clear.
You can try to insert sim card back to slot 1 after 1-2 days.

The only option was left to flash stock firmware, but as it updated to oreo, its bootloader has also been updated so I will suggest you to wait for official oreo firmware to release, please don't try to downgrade your device for now, it can brick your device very badly, keep patience, if any solution will come out, we will definitely tell you

Have you got it fixed now?

Yes, I got it fixed...
1) Just turn off your cellular network.
2) Wait for 1-2 days.
3) Turn on your cellular network again, it should work.
How can I off cellular network. Will keeping it in flight mode helps?

Thank you for raising this question. My phone got the same problem. I am just wondering if I should send it to maintenance center but I guess they will just do reset.
And by saying "turn off cellular network and wait for 1-2 days", do you mean by just turning off the data usage, or turning it to flight mode/ turning the phone.

i face same problem .. Nokia care told me that your phone motherboard problem
Hi All, I have a Moto G5 Plus XT1686 from India. Since yesterday, the both SIMs don't register with the network, even if it does register I am unable to make./receive calls nor messages. I had tried Network reset, From Phone information changed settings to LTE/WCDMA even Factory reset. My phone is still boot loader locked. Anything I could do to reset the phone to working state, before I could get a new SIM. I dont have another phone from which I can check if this is a SIM problems, however I am trying to check that as well.
The problem occured after updating to oreo?

Just before installation, while the notification came up. Oreo seems to work fine, finally narrowed it down to the SIM connectors, so need to get that replaced.
SIMs seems to work fine.

I had the similar issue after oreo update. When i checked *#*#4636#*#* in phone info it showed radio off.
I solved it by flashing modem from the Oreo flashable zip of Soak test 1 and everything is working fine now.
